Fig. 1 Calculated GVD of the designed a-Si:H waveguide. The waveguide is designed to have low anomalous GVD at 1550 nm for efficient and broadband four-wave-mixing. Inset: (a) Cross-sectional schematic and simulated quasi-TE mode profile of the a-Si:H waveguide. The designed waveguide is 198 nm thick and 500 nm wide. (b) SEM image of the fabricated waveguide with ~100-nm silicon dioxide hard mask on top.
